本次部署使用django+nginx+daphne+gunicorn+supervisord
1.每次修改完nginx配置都要重启nginx才能生效
2.daphne支持asgi，本项目用于处理消息通知和私信功能
3.gunicorn是处理动态请求
4.supervisord管理部署的启动项，减少工作量
在装环境的时候，装了一系列的python依赖，但是在后序装一些模块的时候出现gcc错误。仔细排查后发现装的依赖是python2.7的，项目用的是3.6，所以指定特定版本的依赖后问题解决。
邮箱服务器使用qq邮箱，将授权码等写入配置文件即可，使用celery异步处理邮件请求
es能够使用curl访问，但是看日志文件有这些错误

猜测应该是和集群有关，目前还没解决。
